| 发明名称 | Heat-insulating particulate pigment and infrared-reflective coating solution | ||
| 摘要 | Provided is a practical heat insulating particulate pigment having high heat insulating properties. Provided therefore is a heat insulating particulate pigment having a cholesteric resin layer with cholesteric regularity controlled such that, in a wavelength range of 800 nm to 1,900 nm, the cholesteric resin layer has a band of reflecting 40% or more of incident light with a bandwidth equal to or wider than 200 nm. | ||

| 主权项 | 1. A heat insulating particulate pigment comprising a cholesteric resin layer with cholesteric regularity controlled such that, in a wavelength range of 800 nm to 1,900 nm, the cholesteric resin layer has a band of reflecting 40% or more of incident light with a bandwidth equal to or wider than 200 nm, wherein the heat insulating particulate pigment is in a flake form having a median volumetric diameter of 5 to 200 μm, and the cholesteric resin layer is a layer of cross-linked resin. | ||
